› Electronic Stability Control (ESC) is an
active safety system that recognizes
unstable driving conditions at the very outset
and applies automatic and immediate,
corrective action, if necessary.
› Critical Safety system
Chassis & Safety System Example
Electrical Stability Control System
ESC is the sum of the following functions:
ABS Anti-lock Brake System
EBD Electronic Brake force Distribution
TCS Traction Control System
AYC Active Yaw Control
Public
This is how ESC corrects the situation when a vehicle is
under steered:

Mission: Information Management in the Vehicle for Driver &
Passengers – a Key to Realize ‘Clean Power’ and ‘Zero Accidents’
We add new functions by providing a connection
to the outside world as well as value-added services.
With our intuitive and ergonomic human-
machine interface (HMI), we capture
commands, prioritize and present information.

Advanced Driver Assistance Systems
Some Examples
› Adaptive Cruise Control (ACC): ACC follows the flow of traffic
ahead of the vehicle, even if its forward progress is only stop-and-go.
› Blind Spot Detection (BSD): Blind Spot Detection warns the driver
when there are vehicles in the blind spot of the side-view mirror.
Public
› Emergency Brake Assistant (EBA): Emergency Brake Assist
detects critical traffic situations and ensures optimum braking
› Lane Departure Warning (LDW): The Lane Departure Warning
(LDW) driver assistance system alerts the driver with acoustical or haptic
warnings before his vehicle is about to leave the lane.

Automated Driving Systems
Some Examples
› Traffic Jam Assistant: Braking, starting, and adherence to a safe
following distance take place automatically, leaving the driver free to
enjoy his or her favorite music, talk on the phone, or chat with
passengers.
› Parking Pilot: The vehicle connects with the infrastructure and drives
to an assigned parking space completely automatically.
Public
› Highway Chauffeur: If the driver has activated the highway
chauffeur feature, he or she can use that time to talk on the phone,
check e-mail, or just relax and enjoy the multimedia system.

Platform Approach
AUTOSAR: Technical Overview
Modularity
Modularity of automotive software elements enables tailoring of software according to the individual requirements of electronic
control units and their tasks.
Scalability
Scalability of functions ensures the adaptability of common software modules to different vehicle platforms to prohibit
proliferation of software with similar functionality.
Transferability
Transferability of functions optimizes the use of resources available throughout a vehicle´s electronic architecture.
Public
Re-usability
Re-usability of functions helps to improve product quality
and reliability and to reinforce corporate brand image
across product lines.
Standardized interfaces
Standardization of functional interfaces across
manufacturers and suppliers and standardization of the
interfaces between the different SW-Layers is seen as a
basis for achieving the technical goals of AUTOSAR.
The figure on the right hand side shows a very condensed
view of the AUTOSAR approach. The basic concept is the
AUTOSAR Software Component (SW-C).

› Number of ECUs is increasing as more and more functions are provided
› Today, Average is 25 ECUs per vehicle, more than 100 ECUs are embedded on some
luxury vehicles, as a consequence:
› More network connection needed
› Wiring harness weight is increasing
System Integration
Public
› Wiring harness weight is increasing
› More power consumption
› System Complexity is increasing

› Body Control Modules (BCMs) are central elements of vehicle electronics. They combine
several functions in one housing and control practically all the vehicle's electronic basis,
comfort and security functions.
› They make classical standard functions such as actuation of lights and windshield wipers
possible.
› In addition, Body Control Modules are increasingly also integrating further functions like
Passive Start and Entry (PASE) or Tire Pressure Monitoring Systems.
System Integration
Example
Public
› Thanks to their scalable architecture and AUTOSAR-compatible software modules, they
can be freely adapted to satisfy customer requirements and harmonize with a specific
vehicle in order to respond to market demands worldwide.
